PICK.

Specification of Letters Patent.

Patented Oct. 30, 1906.

Application led April 13| Sellafl N0. 311,462-

To au whom, it may concern:

Be it known that I, JAMES B. LUCAS, a citi- Zen of the United States, residing at Valley Springs, in the county of Calaveras and State of California, have invented certain new and useful Improvements in Picks, of which the following is a specification.

This invention has relation to the implements employed in digging, and more particularly to an improved form of pick.

The general object of the invention is to provide a pick or similar tool which is constructed with removable points adapted to be readily replaced should they become worn or broken while in use.

In the application of the invention the pick is formed in sections and comprises a body portion secured to the handle in the usual manner and provided with sockets for the reception of the removable points.

The invention further consists in the peculiar construction of the sockets, which are so formed that a punch can be employed to drive out the old points should they become corroded or wedged therein.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for eHecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a perspectiveview of a pick embed 'ng my invention. Fig. 2 is a longitudina sectional view through same. Fig. 3 is a detail perspective view of the various parts.

Corresponding and like parts are referred to in the following description andindicated in all the views of the drawingsby the same ,reference characters.

Referring to the drawings, the numeral 1 designates the handle-receiving portion of the pick, provided with an opening 2, extending entirely therethrough and designed to receive the handle 3 in the usual manner. The handle-receiving portion 1 is provided at its outer end with oppositely-extending preferably rectangular sockets 4, whose outer sides 7 extend in a plane beyond the outer side of the handle-receiving portion 1, as indicated particularly in Fig. 2. These sockets 4 are intended to receive the correspondinglyshaped Shanks 5 of the pick-points 6, and they are tapered, as shown, so that the pickpoints 6 may be wedged therein and be securely held in place without the necessity of other securing means.

As best seen in Fig. 2, the end walls 9 of the sockets 4 are preferably at right angles to the sides or interior walls of the sockets and extend flush or are coincident with ythe outer edge of the handle-receiving portion 1, but stop short of the outermost walls 7 of the sockets. These bottom walls 9 by their arrangement constitute solid bearing-surfaces for the ends of the Shanks of the pick-points, such surfaces being preferably integral with the remaining portion of the part 1 and at `unduly worn in use, the said point may be readily drifted ont of the sockets by a suitable punch or tool directed against its innermost end at the opening 8. 'N ew points can then be placed in osition and the operator will have practically a new pick. As it is well known that after a pick has been used the points become wedged or corroded in the sockets so that it is practically impossible to remove them except by drifting them out by a punch or the like, the importance of this feature is apparent. At the same time the provision ofthe openings 8, as they extend only partially across the rear ends of the Shanks of the pick-points, does not weaken the rigidity of the sockets as a bearing for the pick-points to any appreciable degree. forming the sockets 4 so that they project partially beyond the end of the body portion 1 has the double advantage of providing a solid bearing for the base of the pick-points and also of forming an opening 8, through which they can readily be drifted out of position.

Having thus described the invention, what is claimed as new is- A pick of the character described, comprising a handle-receiving portion or body provided with a handle-receiving opening and at its outer end with two oppositely and outwardly extending sockets, the outermost walls of the sockets of said portions extending beyond the outer edge of the handlereceiving portion, the opposite or innermost The method of IOO walls of said sockets extending in 'a plane their inn'er ends abutting against the bottom within the margins of said handle-receiving wall 9, while the remaining portions of said portion, and the bottom wallsQofsaid sockets inner ends are flush or coincident with the terminating slightly short of the said outersaid openings 8.
